SELVAGE ATTACHMENT FOR LOOMS.

Specification of Letters Patent.

Patented May 1, 1906.

Application filed October 18, 1904. Serial No. 229,041.

To all whom it mag/concern;

Be it known that I, THEODORE GARIsIO, a

citizen of the United States, residing at South ings, and to charactersof reference marked thereon, which form a part of this specification.

This invention relates to selvage-forming mechanism for looms, and moreparticularly to an attachment that may be placed on either dobby orJacquard looms to form a selvage intermediate the edges of the warp,whereby double or multiple width fabrics can be woven.

Referring to the drawings, in which like parts are similarly designated,Fi ure 1 shows my attachment in its preferred form. Fig. 2 is amodification. Fig. 3 is a second modification. Fig. 4 shows an open shedwith a selvage-forming thread on one side of the warp. Fig. 5 shows thesame thread carried to the opposite side of the warpthreads. Fig. 6shows a center selva e in which two warp-threads form part 0 theselvage. Fig. 7 is a similar view of the fabric, illustrating how morethan two war threads can form part of the selvage to ma e a widerselvage.

Referring more particularly to Figs. 4 and 5, 1 is the warp-beam, 2 and3 a pair of warp-.

threads, 4 and 5 heddles that lift them, 6 is the lay, and 7 the reed,all of usual construction, either of a dobby or Jacquard loom. 8

is a selvage-thread spool from which the self ;eye 11 or in the casewhere a guide-rod 10 is used between the spool 8 and the guide-rodvage-thread 9 passes through the eye 11 of the selvage-forming mechanismand through the reed with the warp-threads. In some cases it isnecessary, depending upon the structure of the loom, to insert aselvage-thread guide 10 to keep this thread as much as possible clear ofthe shed.

At the proper place in the width of the warpsay at the centerwhenweaving double -width fabric having a center selvage this thread isstarted through the eye 11 of the selvage-thread carrier through thereed to the goods-beam. (Not shown.) The selvage-thread eye 1lis at theupper end of the loop 30, shank b, and eye 17, all formed of a singlepiece of wire, the lower end of the loop 30 being a straight twistedshank portion 11, ending in an eye 17, that is connected to theselvage-thread carrier comprising the eye 11,

retracting-spring 31 or weight, as the case may be, to always pull theloop and selvagethread down below the shed.

On the right-hand portion or member of the loop 30that is, that portionof the loop to the ri ht of eye 11there is a selvage-thread li' ercomprising a twisted wire 32, having a loop 15 at its lower end and justabove this loop a loop or open twist 33 above which is the twisted shank32, terminating in an eye 18, to which is attached the harnesscord 24going to the dobby or to the J acquard, as the case may be. T

Through the open twist 33 of the selvagethread lifter passes the loop 34of the selvage-thread retractor, terminating in a downwardly-extendingtwisted wire shank 35, having an eye 12 at its lower end, to which isattached a retracting-spring 36 or a weight, asthe case may be. H

To the left-hand side of the loop is attached similar mechanism, butworking oppositely to that of the right-hand mechanism just describedand consists ofa loop 16 at the lowerend of the twisted wire shank 37,having at .its upper end an eye 19, to which is attached a liftingharness cord 25, connected to the dobby or jacquard mechanism, as thecase may be. Just above the loop 16 is an eye or open twist 38, and intothis takes a loop 39 of a twisted wire shank 40, terminating in an ,eye13, retracted by a spring 41 or a weight, as the case may be.

It will then be seen that there are two selvage-thread lifters operatinggalternately, one for each opening of the shed, as well as theirretractors.

Between the selvage-thread spool and the 10 is the porcelain eye 23,connected by the spring 22 to the warp-thread guide-rod 21.

The operation of the device is as follows:

At or before the time that the shed has been When leasing of theharness-cord 24. When in its lowermost position and the shed iscompleted or nearly completed, the cord 25 is pulled, wire 37 is raised,sliding along the left-hand side of the loop 30 to the eye 11 and thenlifting the loop 30 to the other side'of the two warp-threads to theposition shown in Fig. 5.

Fig. 2 shows a selvage-thread lifter comprising a loop 131, made of flatwire and of a slightly-different form from the loop 30, beingsubstantially triangular in shape. 1 1 l is made, as before, at theupper end of the loop and there is a somewhat elongated eye 117 at thelower end.

In place of having two wires 37 and 40 con? nected by the eyes 38 and 39I use a single wire 140, having a loop 116 with an eye 119 at its upperend and a second eye 113 at its lower end, thus making the retractor andlifter in a single piece. A similar wire 135 acts on the right-hand sideof loop 131. This wire 135 has an upper eye 118, a lower eye 112, and aloop-elongated eye 115. These loops or wires may be double, as shown, bydoubling the flat wire upon itself over a suitable form, or they may bemade solid and stamped from sheet metal. v

In Fig. 3 I have shown the structure somewhat modified. Thethread-carrying eye 211 is formed in a yoke or open-ended loop 231,either made of wire or stamped from sheet metal. Each leg of the yokecarries at its lower end a weight 241 and 236. On the right-hand legslides an eye 215, loosely connected to a lifting-wire 232, and to theretracting-wire 235 is also attached a weight at its lower end, but notshown, a similar weight being shown in connection with the left-handwire 240. On the left-hand leg is an eye 216, loosely connected to alifting-wire 219 and a retracting-wire 240, carrying on its lower end aretracting-weight 241.

Referring to Fig. 6, it will be seen that the warp-threads 2 and 3 havea sinuous selvagethread 9, passing below them, and through eachconvolution of the sinuous thread 9 passes a weft-thread a, saidweft-thread passing under the convolutions of the sinuous thread.

In Fig. 7 there are siX warp-threads embraced in the selvage, theweft-threads a passing under all of the convolutions of the sinuousselvage-thread and the selvage-thread passing under all of thewarp-threads back and forth between adjacent weft-threads.

Having thus described my invention, what I claim as new therein, anddesire to secure by Letters Patent, is
